A valve comprising a body with an inlet, an outlet and a passage fluidly interconnecting the inlet and outlet; a shut-off device of the passage, with an actuating member movable along a longitudinal axis; a hand operating device of the actuating member, for selectively opening or closing the passage, and comprising a support element and a rotating element with at least one contact surface configured for sliding along at least one ramped surface on the support element, or vice versa, so as to convert rotation of the rotating element into a translation of the actuating member; wherein the body comprises two arms extending longitudinally and diametrically opposed relative to the longitudinal axis, with distal ends holding the support element.

A cap member is used in a shut-off valve including a valve head in which a through hole is formed, the cap member including: a cap member main body screwed into the through hole; a first engaging portion for engaging with a first tool for screwing the cap member main body into the valve head; a second engaging portion formed inside the cap member main body to engage with a second tool for unscrewing the cap member main body from the valve head; and a wall portion covering the second engaging portion so that the second engaging portion is not exposed when the cap member is viewed from the first engaging portion toward the second engaging portion.

The invention relates to a quick-opening valve for a pressurized extinguishing fluid vessel, having an extinguishing fluid inlet (4), an extinguishing fluid outlet (5), a flow chamber which extends from the extinguishing fluid inlet (4) to the extinguishing fluid outlet (5), a valve piston (12), a valve seat (10), wherein the valve piston is movable back and forth between an opened-up position and a shut-off position such that the valve piston (12) and the valve seat (10), in the shut-off position, bear against one another in fluid-tight fashion and, in the opened-up position, are spaced apart from one another such that the extinguishing fluid inlet (4) and the extinguishing fluid outlet (5) are fluidically connected to one another. It is proposed according to the invention that the extinguishing fluid inlet (4) and the extinguishing fluid outlet (5) are oriented substantially parallel to one another.

A refrigerant can tap with a tap body having an inlet and an outlet, an internal pin, a gasket, and a backflow preventer. The inlet and outlet of the tap body have a one-half inch ACME left-handed thread, the inlet for engaging the self-sealing valve of an R-1234yf can.

The invention relates to a shut-off valve for controlling flow of a pressurised gas. The shut-off valve comprises a body defining a passage extending between a gas inlet channel and a gas outlet channel, and a sealing element arranged to, in a first position, close the passage, and in a second position, open the passage to allow gas to flow between the gas inlet channel and the gas outlet channel through the passage. The invention also relates to a method for controlling flow of a pressurised gas by means of a shut-off valve.

A valve for pressurized fluid including a body housing a fluid circuit having an upstream end configured to be placed in communication with a reserve of pressurized fluid and a downstream end configured to be placed in communication with a user of fluid, the circuit including a collection of valve shutter(s) including at least one shutoff valve shutter allowing the circuit to be closed or opened, the valve including a member for manually controlling the collection of valve shutter(s).

The present invention relates to a valve assembly configured to be arranged in a cylinder opening of a gas cylinder, comprising a valve housing having a first housing end and a second housing end, a first housing opening arranged at the first housing end and a second housing opening arranged at the second housing end, the first housing opening having an inner diameter, and a bore extending between the first housing opening and the second housing opening, the bore having an inner face, and an inner valve unit arranged in the bore, said inner valve unit having an inner valve housing, and a first end and a second end, the first end having an outer diameter, the outer diameter being larger than the inner diameter of the first housing opening, the first end being configured to abut the inner face at the first opening, whereby a filling valve is provided, the inner face of the first opening being a filling valve seat, the second end comprising an inlet to the inner valve unit, the inner valve unit further comprising a consumption valve arranged at the first end, and a first pressure reduction valve configured to reduce a pressure in the gas cylinder from a first gas pressure to a second gas pressure, wherein the valve assembly further comprises a protection device arranged in connection with and configured to interact with the inner valve unit to hinder unintended gas flow into the gas cylinder. The present invention also relates to a gas cylinder having a gas with a pressure and an opening, to a gas delivering system, to a gas consuming system and to a beverage dispensing system.

Some embodiments include a fluid valve assembly with an outlet base dimensioned to be positioned through a drain in a fluid tank, and a float assembly including a moveable float. The moveable float can form a fluid-tight seal at a first end when the moveable float is coupled to the outlet base, and a flow opening when the moveable float is at least partially decoupled from the outlet base. Some embodiments include a housing positioned with the moveable float, where the housing encloses a suction device coupled to a moveable piston. Some embodiments include an actuable diaphragm positioned in the outlet base, and a compressed air tube or passageway coupled to one side the actuable diaphragm. In some embodiments, the actuable diaphragm is configured and arranged to be actuated by compressed air to move the moveable piston.
